Voleur is an active directory box that starts with assume breach credentials. I’ll find an Excel notebook with credentials and get a shell. I’ll find a deleted user and switch to a service account to recover it. That user can access an SMB share with a user’s home directory backup, where I’ll find DPAPI encrypted credentials. I’ll recover those, getting access to an SSH key that provides access to a WSL instance. There I’ll find registry hive backups where I can dump the administrator hash.

Introduction: Active Directory remains the cornerstone of enterprise identity management, making it a prime target for adversaries. The Certified Active Directory Red Team Specialist (AD-RTS) course by CyberWarFare Labs demonstrates how attack surfaces have evolved beyond traditional techniques to include certificate services, virtualization platforms, and web application vulnerabilities. Learning Objectives: Master advanced AD certificate services exploitation for persistence and privilege escalation…

Introduction: Kerberoasting remains a prevalent attack technique where attackers extract service account Ticket Granting Service (TGS) tickets from Active Directory to crack them offline. However, a critical attribute mismatch can cause standard tools to fail silently, generating uncrackable hashes and creating a false sense of security for both attackers and defenders. Learning Objectives: Understand the technical root cause of AES Kerberoasting failures involving UPN and sAMAccountName mismatches.

TombWatcher is an assume breach active directory box. I’ll use BloodHound to find a path to another user with targeted Kerberoasting, GMSA, ForceChangePassword, and a shadow credential. This user has access to the AD Recycle Bin, where I’ll recover an old ADCS admin account. I’ll use that account to exploit ESC15 to get Administrator access.

Kerberoasting is a post-exploitation technique used by attackers to gain privileged access to Active...

Introduction: In the complex landscape of Active Directory (AD) security, a seemingly minor misconfiguration can lead to a full domain compromise. Kerberoasting is a pervasive attack technique that exploits service accounts to extract crackable credentials, and it all begins with the enumeration of Service Principal Names (SPNs). This article provides a technical deep dive into identifying vulnerable accounts and hardening your environment against this stealthy threat.

I learn about cryptographic vulnerabilities all the time, and they generally fill me with some combination of jealousy (“oh, why didn’t I think of that”) or else they impress me with the brilliance of their inventors. But there’s also another class of vulnerabilities: these are the ones that can’t possibly exist in important production software, … Continue reading Kerberoasting →

Ascension, a major healthcare provider, suffered a massive data breach due to weak passwords and Kerberoasting attacks. Expert Tim Medin reveals how simple oversights can compromise even large organizations.

Introduction: Kerberoasting is a pervasive attack technique targeting Microsoft's Kerberos authentication protocol in Active Directory environments. By exploiting the very tickets designed for secure service access, attackers can offline-crack service account passwords, often leading to significant domain compromise. This article deconstructs the attack from both offensive and defensive perspectives, providing the commands and knowledge needed to understand, simulate, and defend against it.
